Byzantine conquest of Bulgaria complete
Four years after Kleidion, Basil II entered Ohrid and received the submission of the last Bulgarian notables. The First Bulgarian Empire, after three and a half centuries, was extinguished by his patient grinding. Basil rode in triumph through Athens, dedicating his victory to the Virgin at the Parthenon. Bulgaria would not regain independence for nearly two centuries, until the Asen brothers rebelled in 1185.
Mahmud of Ghazni sacks Mathura and Kanauj
The Ghaznavid sultan stormed the sacred Hindu city of Mathura on the Yamuna, where his soldiers marveled at the jeweled idols before smashing them. He then marched to Kanauj, the ancient imperial capital, which surrendered without a fight. The twin raids stripped the Gangetic heartland of its accumulated temple wealth and shattered northern India's remaining political confidence.
Song engineers improve canal lock technology
Along the Grand Canal linking the Yangtze to Kaifeng, Song engineers perfected pound locks with double gates that allowed barges to move between water levels without portage. The innovation transformed China's internal commerce, enabling grain shipments of hundreds of thousands of tons annually and sustaining the world's largest urban population in the northern capital.
Boleslaw the Brave captures Kiev
The Polish king marched across the steppe to install his son-in-law Svyatopolk on the Rus throne. He crossed the Western Bug by personally striking the river with his sword. Kievan townspeople greeted him with bread and salt, then slaughtered his garrison within weeks and drove the Poles home. The expedition marked the high watermark of Piast ambition in the east, never to be equaled.

Within weeks Boleslaw marched east and captured Kiev, briefly installing his son-in-law on the Rus throne in an extraordinary display of Piast power. The peace acknowledged Poland as a force that the Empire could no longer afford to ignore.
